Application filed April 3,

To all 1z0/omit may concern Be it known that 1,' JoHN J. Erinnern, a citizen of the United States, residing at Marietta', in the county ot Lancaster' and State oi Pennsylvania, have invented new and useful lfn'iprovements in Phonograph Turntables, ot' which tie following isv a sp'ecication.

This invention lrelates to phonograph turn-tables and has for its object rto provide a simple, cheap and durable device for guiding or centering phonograph records while they are being placed upon the turntable.

A further object is to provide a device of this character which is applicable to records of different diameter. l

This invention will be more fully understood from the following description, taken in connection with the accompanying .drawing, forming a part hereof, and in which similar numerals refer to similar throughout the several views.

Fig. 1, is a plan view of a phonograph turntable showing ra practical embodiment of this invention.

Fig. 2, is a sectional view on line 2 2.

In the drawing, the turntable t is mounted on the rotatable spindle 5 which extends above the turntable forming a center pin 6. Carried by the base board 7 is a `block 8 curved to fit around the turntable as shown. A plate 9 is secured to the outside surface of the block 8 through studs 10 and nuts 11, and is provided with turned over ends 12. The plate 9 may be raised or lowered through the slot 14 to vary the space between the turned over ends 12 and the top surface of the block 8. y f f The construction shown in the drawing accommodates vtwo sizes of records as indicated at 15 and 16. The top surface of the block 8 is slightly lower than the top surface of the turntable, thereby providing clearance for the large size record 16 as 'indicated at 17. The radius ot' the curved block 8 is slightly larger than the radius 'ott the small size record 15 as indicated at 18. A portion of the turntable is cut away at two places as indicated at 19.

hen placing the small record on the turntable the saine is placed in the position of F ig. 1 taken indicated at 20 in light broken lines Fig 2. y

tablegthis gripping of course taking placeat the side` of the table',l

n account of the largesize record beingvv larger than the 'turntable there is a possibility of the record tipping oit the center pin, if through lack of care and the plate 9 is adjustable vertically so that the space between the turned over ends 12 and the top `surface of the block 8 may be adjusted to accommodate records ofdifferent thickness. 5

To assure that the turntable always stops at the right position to cooperate `with the curved block 8, I provide a positive stopping device in which, 26 is a lever pivoted to the base board 7 through the screw 27.` Forming part of the lever 26 is' a sleeve 28 intowhich is iitted free to slide a hooked shaped rod 29. A spring 30 normally holds the Ahooked shaped rod 29 in the direction indicated by the arrow ,81: with the setv collar' 32 bearing against the end 33 of the sleeve.A

excessive presv vsure is brought upon thev recordY inthe dii shown, and are adapted to engage with the hooked shaped rod 29 when thev lever 26 is in the position shown in Fig. 1, (full lines).

The turntable rotating inthe directionA indicated by the arrow 37 'continues to turn until either of the pins 36 engage with the hooked shaped rodi 29. The rod 29 being free to slide is yielding in its movement against the action of the spring 30; this af-A fords an easy and positive stop for the turn-- table and assures that at all times either of the out away portions of the turntable are in proper position relative to the block 8.

When the lever 26 yis moved to the position shown in light broken lines, the hooked shaped rod 29 is released from the pin and the turn table is free .to rotate.

l Having` thus described my invention, what I claim and desire yto secure byll'nited States Letters Patent is as follows:

l. In combination 'with a phonograph l turn-table, a vcenter pin .on the turn-table,

. and a gauge fixed stationary near the rim of vice, the combination with a rotatable table, v

said turn-table and adapted to guide a record to engage with said pin.

2. In a phonograph record centering device,fth e combination with arotatable table7 of a centery pin on said table, a record supporting memberfixed near the rrim of saidA said member being slightly lower table, than the table, and a gauge extending above said record supporting member and adapted to guide a record to engage with said center pin.A i' Y 3.y In a phonograph record centering `deof a center pin on said table, a record supe porting member fixed near the rim of said table andv adapted to serve as argauge to guide a recordof small diameter to engage with said center pin,v said record sup-porting member being slightly lower than said 'table7 and a gauge extending above said record supporting member and adapted to guide a record of large diameter to engage with ysaid center pin.
